Abstract
828,069. Sensitized photographic emulsions. KODAK Ltd. March 7, 1956 [March 8, 1955], No. 7103/56. Drawings to Specification. Class 98(2) The sensitivity of a washed photographic silver chloride or chorobromide emulsion containing a sensitizing dye of the general formula:- wherein R and R, are alkyl or substituted alkyl groups, X is an anion, Z and Z 1 complete 5-membered heterocyclic nuclei and R 2 is an aryl, substituted aryl, unsubstituted 2-pyrryl or thienyl group or the group:- where R 5 is H, alkyl or aryl, R 6 is H, alkyl, cycloalkyl or aryl and Z 4 completes a 3-indolyl or benz-3-indolyl nucleus or when R, and R 6 are not both H, a 3-pyrryl group, or Z 4 together with R, and R. complete a pyrrocolyl nucleus, is improved by incorporating therein a water-soluble salt of cadmium or zinc in amount from 5 to 35g. per mole of silver halide. The emulsions are further improved by including therein also a dye of the general formula:- wherein R 3 and R, are alkyl groups, Q completes an indanedione nucleus or a 5- or 6-membered heterocyclic nucleus, Z 2 completes a 5- or 6- membered heterocyclic nucleus and Z 3 completes a nucleus of the naphthothiazole or naphthoselenazole series. The cadmium or zinc salt may be the chloride, bromide, sulphate, nitrate, iodide or acetate. In the above formulae, R and R 1 may be methyl, ethyl, n-propyl, carboxymethyl or benzyl, R 2 may be phenyl, tolyl, 2:5-xylyl, chlorophenyl, naphthyl, or 9-phenanthryl, R, or R 6 may be methyl, ethyl, n-propyl, n-amyl, n-heptyl, n-dodecyl, phenyl or tolyl, or R 6 may be cyclohexyl, R, and R 4 may be methyl, ethyl, n-propyl or n-butyl, Z and Z 1 may complete nuclei of the thiazole, benzthiazole, naphthothiazole, benzselenazole, naphthoselenazole, oxazole, benzoxazole, naphthoxazole or benzimidazole series, Z 2 may complete nuclei of the benzthiazole, naphthothiazole, benzselenazole, naphthoselenazole or naphthoxazole series and Q may complete a barbituric acid, thiobarbituric acid or isoxazolone nucleus. The cadmium and zinc salts are said also to stabilize the emulsions against fog. Specifications 412,309, 533,425, 538,857, 740,770, 751, 318, 756,226, 774,780, 783,329 and 783,596 are referred to.
